The XRM-ADC-D3/1G5 is an I/O Module which provides two Analog to Digital converters with a sampling rate up to 1.5GHz.
The design is based around the ADC08D1500 by National Semiconductors. Both channels are 8-bit resolution and sampling rates up to 1.5GHz. It is aimed at applications such as IF/Baseband Signal Sampling.
An external clock source may be used or an internal clock can be used to provide the sampling clock.
An auxiliary I/O port is provided for use as a trigger or general purpose signal.
Separate high speed signals are provided to allow synchronisation across multiple XRM-ADC-D3/1G5 boards.
The built-in thermal monitor allows the user to check the operating temperature of the ADC. Provided as part of the sample design is the functionality to read the temperature of the device, and software to monitor this and recalibrate the ADC if the thermal drift is sufficient. The software will also shut the ADC down if the device starts to go over the maximum operating temperature.
Note: To ensure XRMs and XRM2s cannot be inadvertently installed on non-compatible FPGA platform boards the XRM2 connectors are mounted rotated 180° from those on XRM IO Modules. Most photographs of our mature XRM IO Modules are of the XRM version.
